I use it when I ride a car on a block. Yes of course it is a wrong way to use it.

When exchanging mission oil and defoil, I use it so that it can ride smoothly when riding a tire on a concrete block of about 10 cm in height. Because we have a ring closure at the usual time separately ...

It is easy to use with a hard rubber material. This price is pretty good at Cospa with two sets of one set. I want a string that connects two pieces and a hole that allows a string to pass through on the side. Will not it crack owing to aging or aged deterioration afterwards?
